A target connected coverage(TCC)algorithm is proposed to ensure the network connectivity and coverage of wireless sensor networks.The TCC algorithm minimizes the communication delay and balances the path load by deploying the minimum number of relays to connect the targets and the sink node.The directional sensor nodes deployed around each target are from some cover sets to cover the target,and each target is covered by a cover set during the network duration,and the connected coverage is achieved.The simulation results demonstrate that the maximum and average routing hops between the targets and the sink node in the TCC are smaller than those in other algorithms,and the lifetime of the TCC is optimized.
